On July 14, 2000 the active region NOAA 9077 produced one of the largest solar flares
(3B/X5.7) seen in recent years associated with a violent halo coronal mass ejection
(CME). It had a magnetic classification and the morphology of the
sunspot group and magnetic field changed obviously every day. We present here the
relationship between the large scale motions of the spots and the major flare on July
14, based on precise measurements of the proper motions. We find that: (1) The special
magnetic morphology and quick, successive fragmentation caused the active region to be
always in a high shear configuration; (2) There is a good spatial correspondence between
the direction of the movement of one spotgroup and the place where the filament was cut
off and activated; (3) The motion characteristics of the rapidly emerging flux system
showed a good correlation between spot motions and the largest flares, suggesting that
the initiation of the two-ribbon flare on July 14 was promoted by the successive
emergence of the flux systems. The intensive major flare was always connected strongly
with a newly emerging magnetic flux system (Kálmán 1997). This confirms that
δ-configurations and dynamical processes are important in large flares.
